What's the average finder's fee?

Excuse me, I was wondering if you could provide me with some insight on the average finder's fee in the cryptocurrency and finance industry? I understand that this can vary greatly depending on the nature of the transaction and the size of the deal, but I'm trying to get a general idea of what to expect. Is there a standard range or percentage that is commonly charged for finder's fees in this space? Additionally, how do factors like the complexity of the deal and the expertise of the finder play into determining the fee? I'd greatly appreciate any information you can share on this topic.
